Travel Explained
Can You Bring Medication on a Plane?
Prescription pills, over-the-counter medicine and medically necessary liquids are generally allowed through TSA screening, but the preparation required depends on the medication and destination.
Baggage, Packing & TSA Rules • Travel Explained.

The Quick Answer
Yes. TSA allows pills and other solid medications in both carry-on and checked baggage. Medically necessary liquid medication can also exceed the normal 3.4-ounce limit.
Pack essential medicine in your carry-on, keep it organized and tell a TSA officer about medically necessary liquids before screening. International travelers must also confirm that the medication is legal at their destination.
How to Pack Medication for Air Travel
Medication is generally allowed through airport security in the United States. The Transportation Security Administration permits pills and other solid medications in both carry-on and checked baggage. However, keeping essential medicine in your carry-on protects access if checked luggage is delayed or lost.
TSA does not generally require pills to remain in prescription bottles, although medication laws can vary by state. Original labeled containers can make prescriptions easier to identify, particularly when traveling with controlled substances or crossing an international border. A printed medication list or copy of the prescription can also help if you need medical care during the trip.
Medically necessary liquid medication is exempt from the standard 3.4-ounce liquid limit. According to TSA’s liquid-medication guidance, travelers can bring larger reasonable quantities in carry-on baggage. Tell a TSA officer about the medication before screening and separate it from other belongings if requested. It does not need to fit inside the regular quart-size liquids bag.
Accessories needed to keep medication safe may receive additional screening. This can include freezer packs, cooling pouches, syringes, pumps and other supplies. Keep needles with the medication they support and protect sharp items appropriately. Travelers who need screening assistance can contact TSA Cares before departure.
TSA rules cover security screening—not whether a medication is legal in another country. The U.S. Food and Drug Administration warns that a medicine approved in one country may be restricted or unapproved elsewhere. Before international travel, check the destination’s embassy or health authority and bring information showing the medication’s brand name, generic name, strength and prescribed use.

An Important Distinction
TSA Approval Is Not International Permission
TSA determines whether an item can pass through a U.S. airport checkpoint. Customs agencies and destination-country laws determine whether you can legally bring that medication across a border. A prescription that is routine in the United States may be restricted elsewhere.
